Sample text

For example, the SearchFacade session bean might need to perform some database initialization when it is created or close some database connections when it is destroyed. The application can gain fine-grained control over the various stages of the bean lifecycle via methods known as callback methods. A callback method can be any method in the session bean that has callback annotations. The EJB container calls these methods at the appropriate stages of the bean’s lifecycle (bean creation and destruction).

Container-Managed Concurrency For a singleton session bean using container-managed concurrency, the container manages concurrency by associating each business method with either a shared Read lock or an exclusive Write lock. A Read or Write lock is specified using the @Lock annotation. Listing 2-21 demonstrates container-managed concurrency by using the Read lock on the getShopperCount method and Write lock on the incrementShopperCount method. With this change, multiple clients can get the value of shopperCounter concurrently but access to incrementShopperCount is blocked for all other clients while one client is accessing it.

JPA is widely regarded as a tremendous improvement over the entity beans model defined in earlier versions of EJB. JPA borrows unabashedly from both proprietary and open source models such as TopLink, Hibernate, JDO, and Spring, which gained traction as popular alternatives to the often heavyweight and cumbersome entity bean model defined in earlier EJB revisions. Consequently, like session beans, entities are simple POJOs (plain old Java objects), and apart from a sliver of metadata indicating that they are an entity—captured in a Java annotation or in the persistence XML descriptor—they are a very clean representation of the underlying database table.
